Abstract
The invention relates to a benzoyl peroxide artificial explosive simulant, belonging to the technical field of an energetic material and simulation, and aiming to solve the problems that a hazardous benzoyl peroxide article is highly hazardous when being directly used as a reference for identification of a security scanning instrument and an artificial simulant with the same appearance, color, physical state, density and chemical element composition as benzoyl peroxide needs to be provided. Three formulas are as follows: Formula 1, the simulant is prepared with coumarin, phenanthrene and isoprene according to a mass ratio of 78.3080: 6.2591:15.4330; Formula 2: the simulant is prepared with malonic acid and 3-methylcholanthrene according to a molar ratio of 1:1; and Formula 3, the simulant is prepared with styrene and 2(5H)-furanone according to a molar ratio of 1:1. The simulant can substitute an explosive for correction of the security scanning instrument and other instruments, and hidden security risks can be avoided.
Description
Technical field
The present invention relates to the full emulation explosive simulant of peroxo-benzene, belong to energetic material and imitation technology field.
Background technology
Along with the terror upgrading, anti-terrorism strength is constantly strengthened, and terrified trial of strength with antiterrorism also will continue for some time.It is the object of terrorist attacks that airport, station, harbour and crowd concentrate the local and important place of comparatively dense always.Thereby various countries strengthen all should carrying out safety inspection to the luggage in various different paths and personnel's belongings.Safety check appearance recognition material needs corresponding reference before whether being the explosion hazard article.Generally, explosion hazard article material object should not be directly as object of reference, mainly be since the insecurity of explosion hazard article and people to the fear property at heart of explosive.Especially on the airport, safety check places such as station, harbour, to the periodic check of safety check appearance or demarcate more outstanding.
With peroxo-benzene is example, and these hazardous substance are a kind of colourless liquids, and explosive extremely strong and unusual unstable has friction very easily to blast slightly, and its brisance and TNT are close, adopt true explosive in carrying out verification or calibration process, to have high danger.
With the sample of stand-in as judgement explosion hazard article; Can distinguish the explosion hazard article from aspect emulation such as outward appearance, color, states of matter, density, chemical element compositions, can help global security staff and public security system personnel reducing under the factor situation such as dangerous instability verification as far as possible or demarcating the explosion hazard article to a certain extent.
Though the U.S., Britain and Israel have also prepared the stand-in of some liquid explosive; Aspects such as its outward appearance, form and density are close with true thing; The ordination number aspect is also close with true explosive, but aspect such as elementary composition, element percentage content and color is different from true explosive, can not reach should producing effect of full emulation; Can only be x ray level emulation, influence the accuracy of safety check appearance recognition material.But up to the present, do not retrieve peroxo-benzene stand-in and related data thereof.
Summary of the invention
The objective of the invention is in order to solve with the peroxo-benzene hazardous substance object of reference of directly discerning in kind as the safety check appearance; Has high danger; And the full analogue simulation thing that has aspects such as identical appearance, color, states of matter, density, chemical element composition with peroxo-benzene is provided; When guaranteeing safety check appearance recognition material accuracy, avoided adopting the danger as object of reference in kind again.
Mentality of designing of the present invention is: according to peroxo-benzene is elementary composition by three kinds of CHO etc., and molecular formula is C
12H
10O
2, the percentage composition of each element is: C 77.40%, and H 5.42%, and O 17.18%; The stand-in element percentage composition of desire preparation is identical; Molecular formula is identical with relative molecular mass, at first structure is designed, according to the molecular formula of peroxo-benzene; The present invention adopts the smallest common multiple method; Aspects such as the smallest molecule of therefrom finding out stable existence with method for splitting and factorization is again assembled, and makes every effort to stand-in in element percentage composition, color outward appearance, density are consistent with true explosive.
1, elementary composition and characteristic is confirmed
Take all factors into consideration according to element that constitutes in the peroxo-benzene molecular and elementary composition percentage composition, take into full account the element percentage composition, ordination number; Density; Factors such as color outward appearance, peroxo-benzene is split or with peroxo-benzene molecular formula and elementary composition expansion n doubly, like 2 * C
12H
10O
2=C
24H
20O
4, split compound is elementary composition then, select the mixed in theory composition of micromolecular compound, the element percentage composition of its mixture is identical with peroxo-benzene.
2, finding the solution simulation with ordination number forms
Calculate according to the method for formula (1) composition and the ordination number to peroxo-benzene, through calculating, have only elementary composition percentage composition approaching more, ordination number could coincide, and is just more accurate with explosive peroxo-benzene molecular.
3, accurate measurement, premix and assembling stand-in.
Not being simple mixing in process for preparation, if solid matter mixes each other or solid-liquid mixes, then is that a part of material is heated to fusing point; Make its fusing back make preparatory composite A in advance with other component; Treat the third material to be added after complete dispersing and mixing evenly again, under high-speed stirring and intensification condition, assemble, the material that has is then through disperseing; Solve intermiscibility; Should make organic element parcel water molecules (when mainly being meant trace water content) as moisture, make stand-in have good intermiscibility, not present demixing phenomenon and obtain corresponding explosive simulant.If liquid mixes each other, the mutual miscible assembling of direct two kinds of liquid gets final product.
The objective of the invention is to realize through following technical scheme:
Fill a prescription as follows for three kinds of the full emulation explosive simulant of peroxo-benzene of the present invention:
